A control system for an electrified powertrain of an electrified vehicle determines whether to enable/disable a power dissipation mode of the electrified powertrain and, when the power dissipation mode is enabled, determines a target power dissipation based on a driver torque request and a set of operating parameters of the electrified vehicle, determines an allocation or distribution of the target power dissipation between a set of available power dissipation systems from a plurality of power dissipation systems, optimizes the allocation or distribution of the target power dissipation between the set of power dissipation components, and controls the available set of power dissipation systems based on the optimized allocation or distribution to achieve the target power dissipation and thereby reduce a thermal load on a friction brake system of the electrified vehicle.
